c32edff2bb uti: rename x86-specific 'fs' to 'tls' + arm implem
Note: the original fujitsu implementation didn't rename the various
save_fs function/desc to save_tls for some reason, might as well go all
the way though...

516ab87ab9 Copyrights: fujitsu 2018 bump
Separate copyright bumps in a different commit.
A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

fb9832af6d perf counters: add arch-specific perf counters
arch perf counters are placed at start, so offset all
other counters (because placing arch perf counters at the end
wouldn't have been intrusive enough?)

59828db5c9 mcctrl archdeps: rename vdso_image_64 to _vdso_image_64
The symbol appears in some header in some linux version,
it's still not exported so we need our own lookup anyway; just rename it.

e8f8660b73 mcctrl: lookup unexported symbols at runtime
Instead of parsing System.map, use kallsyms_lookup_name() to
get unexported symbols addresses at module loading time.

This lets mckernel work with kaslr enabled (it gets enabled by
default from el7.5 onwards)
